ABSTRACT OF THE DISCLOSURE GAS TURBINE ENGINE INFRA-RED RADIATION SUPPRESSOR A gas turbine engine infra-red radiation suppressor comprising an exhaust nozzle which is surrounded by a duct having a plurality of diffuser vanes at its downstream end. The exhaust nozzle and duct constitute an ejector which is powered by the exhaust efflux from the exhaust nozzle and draws ambient air into the duct through a gap between the exhaust nozzle and the duct. The air serves to cool the exhaust efflux and thereby reduce its infra-red radiation emmission, and the diffuser vanes prevent direct line of sight of the hot exhaust nozzle.
